*JKAzrael had implanted the idea of this in my brain some time ago, but it took Apocalypto and a couple other images on dA to get me to do it XD

I haven't come up with a name for them yet, but they not exactly Astartes and not exactly Renegades. Most of their weapons are poisonous and the majority are directed toward close combat, kinda like the Space Wolves. Their emblem is that fanged skull with the snake in its mouth.

Reminds me of the Rainbow Warriors, they're a Chapter from the old lore rumored to have been named after a Greenpeace ship that got sunk in the 80's. They've never gotten any love from GW but the fandom has weaved their own personality and lore for the Rainbow Warriors, giving them a very Aztec/Mayan/Inca theme and imagining their homeworld Prism as a equatorial jungle planet.Though rare, I've seen one or two converted models and even a piece of fanart here and there. A guy named Greyall on the Bolter and Chainsword forums even did a Rainbow Warrior version of the 6th Edition rulebook cover art: [link]

Cool, actually these people need only there religious zeal to make tham a hell of a soldier but with narcotics and other drugs you have a --- XD. NICE. Um but what kind of projectiles is he using?? I can only think of shuriken like projectiles because we-e-ll these dudes are the kings of the primitive universe. (No offense just taking it into the context you have given us.)
